'96 Chevy Corsica w/ 2.2L engine Will Not Start

Help! I was driving down the highway @ 65 mph. when my car died suddenly, just like you turned the key off, but all of the instument lights and gauges stayed on. I coasted to the side of the road and tried to start the car many times. It turned over, but never fired up. I towed the car home and used my OBDII scanner to check the codes. I retrieved the P0342 code, "Camshaft position sensor circuit". I removed the sensor and inspected it. Yep, it is a sensor alright. I took it apart and found that it is actually a Hall I.C. sensor and there is really no way to check it. I replaced the sensor ($71.99) and the spark plugs. Still no luck. I do have fire at the plugs, and I have gas. When I replaced the plugs, they were wet with gas, and I disconnected my gas line to the fuel rail while I turned the engine over and lots of gas came out. Also, I can smell gas after I try to start the car numerous times.
Can anyone tell me why I never get fire from any cylinder, nor do I get any back firing. If you have spark and gas, why no combustion? I checked the compression with my thumb, with one of the plugs removed, and there seems to be at least some compression.

Thank you for your help,

Mike

If you remove your cam shaft pos sensor, does the shaft spin around or does it sit still when cranking the motor ?
Also have someone crank while you in the oil spout in the valve cover to see if the valves and cam shaft are moving.
I think the timing belt broke.

Methinks the chevy 2.2 is chain driven, but your theory is definitely worth inspecting.........If the cam IS turning, you're going to need a "noid light" to see if you have injector pulse..........Pressure to the rail is one thing, but if the ECM isn't pulsing the injectors, you essentially have "no fuel"

Thanks for replying fellas. I will check the camshaft for movement. I hope the chain is not broke. Would I still get fire to the plugs, and gas in the chambers if the chain broke?

Thank you,

Mike

I checked the camshaft and it is not turning. The timing chain is apparently bad. Thank you for the help.
